I am trying to submit my VAT return but all day the system has said "We can't connect to HMRC right now"

Hi Malcolm 11,

I understand your experience with the CLIENT_OR_AGENT_NOT_AUTHORISED error message and the time you spent trying to resolve it. I also know how it feels when you're directed to seek help from one place only to be redirected back to us. Let me help you out.

The error message you received means you need to reauthorise your account. When setting up the connection between QuickBooks and HMRC, it's crucial to remember that you need to reauthorise the connection every 18 months. This is a security requirement from HMRC to safeguard the data transmitted from your QuickBooks account to HMRC.

Reauthorising the connection is a simple and swift process that only requires a few moments of your time. Rest assured, we'll send you a reminder when it's time to do so, and all you'll need to do is enter your login details. Once that's done, we'll take care of everything else.

Disconnect your account.

1. Click the Gear icon and select Account and settings.
2. In Advanced, select Making Tax Digital.
3. Hit Learn how to connect and follow the steps.

Reconnect your account.

1. Go to the Gear icon and choose Accounts and settings.
2. In the Advanced section, select Learn how to connect.
3. Select Let's go, this will take you to the HMRC page. Once you have read the guidelines, select Continue.
4. Enter your HMRC credentials to sign in.
5. Select Grant Authority and the HMRC page will close.
6. Back in QuickBooks, select Continue.
7. Go to Taxes, and check that the MTD badge is enabled.
